When the background of an image is removed, the product appears flat and unattractive. With shadowing the finished picture gets a realistic depth effect and helps the product stand out. Shadows give the viewer an indication of the spatial relationships between the object, light source and surface. When objects are separate from their background, they lose their natural location in space. With the help of the correct shadowing, objects can be placed into a picture and give the impression of natural lighting conditions. There are numerous types of shadowing like natural, reflection or drop shadow.
